This presentation will outline a lesson in quadratics using geogebra and activotes. The lesson resources are below. I have provided them in various formats such that hopefully everyone will be able to view them.
There is a roundtable discussion on Geogebra and Geometer's Sketchpad later in the day.
Carin begins with the "tickertape" feature on the Promethean board for use with a walk-in activity.
Geogebra is similar to Geometer's Sketchpad, but it is a free download.
This use has begun with a quick review of what a quadratic is. She has a standard form quadratic where the students can apply a change to a, b, and c to show how the change affects the parabola, allowing the students to explore the different parts of a quadratic. This could be altered for use with other types of equations, as well (lines, cubics, etc.).
Next, we look at an interactive simulation for projectile motion. With this applet, students are trying to shoot a target with a cannon, realizing that they are moving the projectile through parabolic motion. Some student may realize that this is a version of a tanks game, where students shoot at targets with a tank. This can allow you to make a connection to math through games.
Gretchen takes over, directing us to this wikispace. She shows us some of the resources that go along with the project.
Question for Gretchen: Do you prefer Geogebra or Sketchpad? Really, they offer many of the same options. The big thing is to get comfortable with what you use. You can find files for use for either to allow for immediate use. There are tutorials for both available online. It's not about the application, but what you do with the application, and they both offer a similar approach for use.
Geogebra also offers files to access as flash files through their website. Geogebra does not need downloaded, as there is web access. If you are looking at having your students do constructions, you will want to have it downloaded.
Time is provided to session attendees to access Geogebra and play around with it.
